A fully explicit fluid-structure interaction approach based on the PFEM [PDF]

, 2017
The efficient numerical simulation of fluid-structure interaction (FSI) problems is of growing interest in many engineering fields. In the present work, a staggered approach for the solution of the FSI problem is proposed. The fluid domain is discretized

Partitioned simulation of the interaction between an elastic structure and free surface flow [PDF]

, 2010
Currently, the interaction between free surface flow and an elastic structure is simulated with monolithic codes which calculate the deformation of the structure and the liquid–gas flow simultaneously.

Modelling and simulation of the effect of blast loading on structures using an adaptive blending of discrete and finite element methods [PDF]

, 2011
We present a new computational model for predicting the effect of blast loading on structures. The model is based in the adaptive coupling of the finite element method (FEM) and the discrete element method (DEM) for the accurate reproduction of ...

On particle finite element methods (PFEM) in dynamic solid mechanics problems

, 2009
The work presents the most relevant features of a numerical simulation setting based on the Particle Finite Element Method. The method is especially suitable for dynamic problems in computational solid mechanics where a fluid-like behavior is experienced by the solid i.e.: metal forming processes, powder compaction processes and granular flows ...
